UNSW : UNSW Atmosphere Study Guide
Atmosphere Study Guide 14 Explore (teacher’s page) Teacher’s information The aim of the Explore section is for the students to investigate some of the ideas around the atmosphere and its characteristics. It is intended that the students make their own discoveries as they work around the stations in the room. Some of the stations are demonstrations that can be done as a whole class at the beginning or end of the lesson. Many of the activities will need preparation a couple of weeks before the start of the unit. The table below lists the equipment and preparation required. Station name Materials list Demonstration: Egg in the bottle – conical flask – peeled boiled egg – taper – matches Demonstration: Shrinking marshmallow – marshmallow with a smiley face drawn on it – vacuum pump – bell jar Demonstration: Collapsing can – aluminium can – Bunsen burner – tripod – gauze mat – matches – plasticine or blue-tack (large ball) Demonstration: Lightning Van de Graaf generator Teacher’s note: this station requires only the generation of the spark from the generator but if you have the time and the equipment you can show the effects of static electricity on objects as well. Floating water – conical flask (100 or 250 mL) – water – playing card – sink Air has mass? – balloons – beam balance or digital scales Making clouds – watch glass – Bunsen burner – tripod – gauze mat – matches – ice Atmosphere summary A computer to access: www.teachersdomain.org/asset/ess05_int_vertical Bernoulli’s principle A5 piece of paper How far up do they go?

Please make one or more copies of these images/words and cut them out prior to the activity. Each set can be paper clipped together or stored in an envelope. RESOURCETEACHER’S
